ABSTRACT

A method for facilitating communication between a wireless client and a network is disclosed. The method comprises communicating information between the wireless client and the network prior to associating the wireless client to the network. The information can be related to setup features or services.

TECHNICAL FIELD

The present invention relates generally to wireless networking. Thepresent invention relates more particularly to a method and system forenhancing wireless device setups and access point selections.

BACKGROUND

Wireless networks for both business and home use are rapidly becomingpopular. Wireless networks provide convenient networking and Internetaccess by eliminating the need for wired connections between computersand other network devices, e.g., routers, printers, storage devices,etc.

Wireless networks are especially convenient for users of portablewireless clients, such as laptop computers, notebook computers, personaldigital assistants (PDAs), and the like. Such wireless clients caneasily be transported between hotspots (locations where wirelessnetworking/Internet access is provided). New hotspots are appearingfrequently at such locations as airports, malls, coffee shops,restaurants, and hotels.

The 802.11 family of standards (Wi-Fi) provide examples of contemporarywireless networks. The 802.11 family of standards is expanding toprovide enhanced features, such as more channels, better security, andgreater bandwidth. An increasing variety of wireless client device typesbased on 802.11 technologies are being developed. Many of these devicesare personal computing devices. However, other types of devices, such ascameras and music recorders, are also being developed.

Connection of a wireless client to a wireless network is facilitated byan access point. Access points contain radio transceivers that providewireless communication to wireless clients and also contain networkinterfaces, such as Ethernet ports, that provide wired communication toa network. An access point may optionally comprise a router and/orswitch, to facilitate communication among computers on the network. Forexample, an access point may contain an Ethernet port that facilitatesconnection thereof to the Internet, such as via a cable modem or adigital subscriber line (DSL) modem, and may also contain a plurality ofswitched ports that each facilitates communication with one or morelocal area network (LAN) computers.

According to contemporary practice, a wireless client can passivelydiscover some information regarding available wireless networks viainformation elements provided in the beacon that is broadcast from eachaccess point. Alternatively, a wireless client can actively discoversome information regarding a single network via a probe request directedto a specific access point. Similarly, a series of probe requests can beused to actively discover information regarding a plurality of knownnetworks.

The information provided to wireless clients via beacons and proberesponses is very simple. It is typically limited to such parameters asnetwork name or SSID, security status, and country code information(e.g., regulatory domain)

However, in many instances it would be beneficial for the wirelessclient to learn more detailed information about the access point or thewireless network. For example, it would be beneficial for the wirelessclient to learn information regarding setup features of the access pointand/or services offered by the network. Such information may allow thewireless device to intelligently select the best access point forintended use and may also allow the access point to optimize eachconnection on a per client basis, thus providing enhanced service to thewireless client.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A method and system for optimizing wireless device setups and accesspoint selections is disclosed. According to one aspect, the presentinvention comprises communicating information regarding a network froman access point to a wireless client and/or communicating informationregarding the wireless client from the wireless client to the accesspoint. In either instance, the information is communicated prior to thewireless client associating to the network. In this manner, suchinformation is communicated and decisions are made based thereon priorto the wireless client associating to the network, such that the need tosubsequently re-associate to a different network is mitigated.

More particularly, according to one embodiment the present inventioncomprises a method for facilitating communication between a wirelessclient and a network, wherein the method comprises communicating abeacon from an access point and the beacon comprises informationregarding available setup features and/or information regardingavailable services.

According to another embodiment, the present invention comprises amethod for facilitating communication between a wireless client and anetwork, wherein the method comprises communicating a probe request froma wireless client to the network and the probe request specifies setupinformation and/or available services.

Referring now to FIG. 1, a wireless client such as a laptop computer 13can communicate with a network, such as local area network 12 or theInternet 10, via an access point 11. Laptop computer 13 can comprise acircuit 15 for communicating a probe request. For example, circuit 15can comprise an 802.11 transceiver.

Access point 11 can comprise a circuit 14 for communicating a beacon.For example, access point 11 can comprise an 802.11 transceiver.

As those skilled in the art can appreciate, the wireless client canalternatively be a notebook computer, a personal digital assistant(PDA), or a telephone (such as a telephone with 802.11 capabilities).Indeed, the wireless client does not need to be either portable or acomputer. For example, the wireless client can alternatively be aprinter, a data storage device, a camera, a music storage device(including portable music storage devices such as MP3 players andiPods), a video player, or any other device that is capable ofcommunicating with a network. Thus, the discussion herein of a laptopcomputer as a wireless client is by way of example only, and not by wayof limitation.

Similarly, the use of an access point as the means by which the wirelessclient communicates with the network is by way of example only, and notby way of limitation. Those skilled in the art can appreciate thatvarious devices may similarly be used and that the term access point canbe considered generic with respect thereto. For example, access point 11can comprise a router, gateway or other device or combination ofdevices. Thus, the access point can be either a standalone device or canbe integrated with one or more other devices, such as gateways, routers,or switches.

According to one aspect of the present invention, the wireless clientdetermines whether or not it is appropriate to associate to a particularaccess point (and consequently to a particular network) prior toactually associating thereto. That is, the wireless client can chose toassociate to a selected access point for among a plurality of availableaccess points. This chosen access point is selected based upon the setupparameters and/or services that are available therewith. For example,the access point may be selected because it has acceptable cost,provides convenient enrollment and provides desired Internet services.In this manner, less time is wasted associating to a network,determining that the network is not suitable for the intended use,leaving the network, and finding a new network to associate to.

Information regarding setup and/or services can be communicated from theaccess point to the wireless client either via a beacon that isbroadcast from the access point or in a probe response that iscommunicated from the access point to the wireless client in response toa probe request from the wireless client.

Referring now to FIG. 2, the use of a beacon to broadcast informationregarding setup and/or services is shown. A plurality of access points(an example of which is access point 11 of FIG. 1) each broadcast abeacon containing setup and/or services information, as indicated inblock 21. A wireless client (such as laptop computer 13 of FIG. 1),which is within communication range (within the hotspot) of the accesspoints, receives their beacons, as indicated in block 22.

The laptop associates to one of the broadcasting access points thatprovide the desired setup and/or the desired services, as indicated inblock 23. The desired setup and/or the desired services can be definedby a user of the laptop, optionally before entering the hotspot. Thedesired setup and/or services can also be inferred from the type ofwireless client, the configuration of the wireless client, the softwareinstalled on the wireless client (including both the operating systemand application programs), and/or data files stored on the client.

For example, for a wireless client having only pictures (images) storedthereon, it can be inferred that a desired service is the transferringof images to a user's web site. This inference would be particularlyappropriate if the wireless device is a camera or camera phone.

Referring now to FIG. 3, the communication of probe requests to aplurality of access points so as to obtain information regarding setupand/or services is shown. A laptop communicates a probe request to aplurality of access points as indicated in block 31. The probe requestcontains information regarding desired setup and/or desired service(s)for the laptop.

Those access points that are capable of providing the desired setupand/or desired service(s) communicate a probe response to the laptopcomputer, as indicated in block 32. Those access points that are notcapable of providing the desired setup and/or desired services do notrespond. The laptop computer then associates to the first access pointto respond that it can provide all of the desired setup and/or services.Alternatively, the laptop computer can select from any one of the accesspoints that respond.

Alternatively, those access points that are not capable of providing allof the desired setup and/or desired services, but are capable ofproviding at least some of the desired setup and/or desired services,communicate a probe response to the laptop computer. Thus, if no accesspoint is capable of providing all of the desired setup features and/orservices, then the wireless client can, if desired, associate to aselected one of the access points that is capable of providing at leastsome desired setup features or services.

Referring now to FIG. 4, a network device 41 and a wireless device 42,are configured so as communicate prior to associating wireless device 42to a network of network device 41. In this manner network utilizationefficiency is enhanced by determining whether or not wireless device 42should associate to the network prior to actually doing so. Thus,associations of wireless devices with networks which are not beneficialcan be avoided.

One example of a suitable network device is an access point, asdiscussed herein. However, as those skilled in the art will appreciate,network device 41 can comprise any device that is in communication withthe network and which is capable of communication with wireless device42.

Wireless device 42 can comprise a mobile wireless device such as alaptop computer. However, as those skilled in the art will appreciate,wireless device 42 can alternatively comprise a non-mobile device suchas a desktop computer.

Network device 41 comprises a memory 43 within which are stored aplurality of information elements. Memory 43 can be located outside ofnetwork device 41. These information elements are discussed in detailbelow. One or more information elements can be broadcast viabeacon/probe response transmitter 44 as part of a beacon, so as to allowwireless device 42 to better determine if association to the network isdesirable.

One or more information elements can be broadcast via beacon/proberesponse transmitter 44 as part of a probe response after a proberequest is received by probe receiver 45 of network device 41. Again,this allows wireless device 42 to better determine if association to thenetwork is desirable.

Beacon/probe response transmitter 44 and/or probe receiver 45 can bedefined by a transceiver, such as an 802.11 transceiver. Alternatively,beacon/probe response transmitter 44 and probe receiver 45 can be anyother type of transmitter and receiver.

At least one aspect of the present invention leverages the informationelement of the 802.11 standard so as to convey wireless client details(or preferences) to an access point. These details can be inserted intothe probe request.

Similarly, at least one aspect of the present invention leverages theinformation element of the 802.11 standard so as to convey access pointdetails to a wireless client. This can be inserted into the beaconand/or probe response.

The information elements can be implemented in a variety of differentways. Each information element can be implemented as a separateinformation element in accordance with the 802.11 specification. Similarelements can be combined into a fewer numbers of separate elements orcan all be combined into a single element. In any case, the informationcan be encoded by the client or access point and sent in the informationelement(s). The access point or client can then decode the element(s)and parse out the needed or desired information.

One aspect of the present invention thus comprises extending theinformation element portion of the existing 802.11 specification so asto facilitate the sending of additional data about the client to theaccess point and for the access point to learn more about the wirelessnetwork environment so the wireless client can make better decisionsabout connectivity, access point selection, services, availablefeatures, etc.

Examples of information elements that can be used according to at leastone aspect of the present invention are discussed below.

WAN Connection Type Information Element

The client can convey the preferred WAN connection type to wirelessaccess points by using a WAN Connection Type Information Element in aprobe request. Conversely, the access point can convey the existing WANconnection type to wireless clients by using a WAN Connection TypeInformation Element in a probe response or beacon. This is aninformation element that uses a defined syntax to communicate thepreferred WAN connection type from client to access point and returnsthe actual WAN connection type to the wireless client. In the lattercase, an access point not meeting the preferred WAN connection type maychoose not to respond to the probe request from the client.

An example of syntax can be 0=dial-up, 1=basic rate ISDN, 2=DSL,3=DOCSIS, 4=Frame, 5=Fiber, etc.

The wireless client can then use this information to configure services,including available or anticipated data rate, and thus select the bestwireless network to support the intended use.

WAN Connection Speed Information Element

The client can convey the preferred WAN connection speed to wirelessaccess points by using a WAN Connection Speed Information Element in aprobe request. Conversely, the access point can convey the existing WANconnection speed to wireless clients by using a WAN Connection SpeedInformation Element in a probe response or beacon. This is aninformation element that uses a defined syntax to communicate thepreferred WAN connection speed from client to access point and returnsthe actual WAN connection speed to the wireless client. In the lattercase, an access point not meeting the preferred WAN speed may choose notto respond to the probe request from the client.

An example syntax can include two separate information fields (one fordownstream, one for upstream) and can convey the provisioned connectiondata rate (e.g., in kilobits per second) for the access point via theinformation element (i.e., downstream=1024 or upstream=128).

The wireless client can then use this information to configure services,setting data rate expectations, and select the best wireless network tosupport the intended use. It is worthwhile to note that the informationconveyed may not be actual throughput experienced on the network but thephysical WAN connection rates.

NAT/NAPT Information Element

The client can convey the preferred NAT/NAPT scenario to wireless accesspoints by using a NAT/NAPT WAN Information Element in a probe request.The access point can convey to the wireless clients whether it islocated behind a NAT or NAPT device by using this information element ina probe response or beacon. This information can be important forservices that the wireless client wishes to establish or use because aNAT or double NAT can block specific applications.

An example syntax can be 0=no NAT, 1=NAT present.

VPN Information Element

The client can convey the preferred VPN utilization to wireless accesspoints by using a VPN Information Element in a probe request. The accesspoint can convey to the wireless clients whether it supports VPN-typeconnections by using this information element in a probe response orbeacon. This information can be important for services that the wirelessclient wishes to establish or use especially if VPN is required by theclient or service.

An example syntax can be 0=no VPN support, 1=VPN passthrough, 2=VPN viasoftware, 3=VPN hardware accelerated. Or the syntax can include the typeof VPN connection supported by the access point such as IPSec.

QoS Information Element

The client can convey the preferred QoS support to wireless accesspoints by using a QoS Information Element in a probe request. The accesspoint can convey to the wireless clients whether it supports or is usingQoS features by using this information element in a probe response orbeacon. This information can be important for services that the wirelessclient wishes to establish or use and require a specific level of datarate or priority. For instance, a WiFi handset can prefer access pointsthat have QoS turned on and have a QoS mapping on the WAN side to ensurethe best call quality. Note: although 802.11e specifies that QoScapabilities of the Wireless LAN (WLAN) be advertised by an individualAccess Point (AP), and that preferred QoS for a client can be conveyedvia use of a Traffic Spec (TSpec), these are fundamentally indicationsof the local QoS between client and AP. The intent of the informationelement described in this section is to indicate the nature of QoS inthe overall network (including upstream and/or downstream broadbandconnectivity).

An example syntax can be 0=no QoS support, 1=QoS LAN based only, 2=QoSon WAN only, 3=QoS on LAN and WAN. Or the syntax can include the type ofQoS connection supported or active on the LAN and/or WAN.

Upstream Network Utilization of AP Information Element

The client can convey the preferred network utilization upstream of theaccess point utilization criteria to wireless access points by usingthis information element in a probe request. The access point can conveythe current utilization of resources to the wireless client using thisinformation element in a probe response or beacon. This can be anessential piece of information in the selection of the best accesspoint. If the network upstream of the access point is over subscribed orover utilized then the service for the wireless client may be degradedor disrupted. In this case, it can be beneficial if the wireless clientknew the utilization of the network resources that the access point isattached to and can choose to associate to a different access point ifneeded. Alternatively, an access point connected to a network notmeeting the utilization criteria indicated in a probe request from aclient may choose not to respond to the probe request. Note: although802.11e specifies that utilization of the Wireless LAN (WLAN) beadvertised by an individual Access Point (AP) in terms of number ofattached clients and percentage of utilized (or available) capacity,these are fundamentally indications of the local utilization betweenclient and AP. The intent of the information element described in thissection is to indicate the nature of utilization in the overall networkthat the AP is attached to.

An example syntax for this information element can be percentutilization normalized to some number (e.g., 0=0%, 255=100%) , , ,

Managed Access Point Information Element

The client can convey the preferred managed access point criteria towireless access points by using a Managed access point InformationElement in a probe request. The access point can convey whether or notit is remotely managed via this information element in a probe responseor beacon. An access point that is remotely managed is often a betteraccess point for a nomadic wireless client because it may have betterQoS or SLAs, i.e., it is more likely to be a public access pointowned/operated by a service provider. For instance, an access point froma nearby house or apartment is unlikely to be remotely managed andproviding this information can help a nomadic wireless client to selectthe best access point. Additionally, certain services being establishedor used by a nomadic wireless client may require a remotely managedaccess point. An access point not meeting the management criteriaindicated in a probe response from a client may choose not to respond tothe probe request.

An example syntax can be 0=unmanaged, 1=managed

AP Owner/Operator Information Element

The client can convey the preferred access point owner/operator criteriato wireless access points by using an access point Owner/OperatorInformation Element in a probe request. The access point can convey itsowner/operator via this information element in a probe response orbeacon. The owner/operator information can be a critical bit ofinformation when the wireless client selects an access point. Forinstance, if the client is a Sprint PCS dual mode (cellular/WiFi) phoneand one available access point is owned/operated by Sprint PCS and theother is owned/operated by T-Mobile it is important that the wirelessclient select the access point owned by Sprint PCS. This can enablespecific services, provide better service, and eliminate any potentialroaming/network charges. As another example, if the wireless device is aCingular dual mode phone and Cingular has a roaming agreement withT-Mobile it can be important for the wireless phone to select theT-Mobile owned access point. An access point not meeting theowned/operated criteria indicated in a probe response from a client maychoose not to respond to the probe request.

An example syntax can be owner/operator=SprintPCS (or other descriptorof the owner of the AP).

AP Manufacturer Information Element

The access point can convey the manufacturer of the access point viathis information element. Certain services, features, or other items mayonly be available on access points made by certain manufacturers and thewireless client can make a better selection with this information.Access points with known issues or incompatibilities can also beavoided.

An example syntax can be manufacturer=Linksys (or other descriptor ofthe manufacturer of the AP).

AP Model Information Element

The access point can convey the model of the access point via thisinformation element. Certain services, features, or other items may onlybe available on certain models of access points and the wireless clientcan make a better selection with this information. Access points withknown issues or incompatibilities can also be avoided.

An example syntax can be model=WRT54G (or other text descriptor of themodel of the AP).

AP Type Information Element

The access point can convey the type of the access point via thisinformation element. The wireless client can chose to associate withspecific types of access points to reduce latency, etc. For instance, awireless repeater can have lower bandwidth and higher latency than awireless router connected directly to the network on the WAN side.

An example syntax can be aptype=bridge, aptype=router, aptype=repeater,etc. (or other descriptor of the type of the AP).

AP Firmware Version Information Element

The access point can convey the firmware version of the access point viathis information element. Certain services, features, or other items mayonly be available on certain firmware versions of access points and thewireless client can make a better selection with this information.Access points with known issues or incompatibilities can also beavoided.

An example syntax can be firmware=1.2 (or other descriptor of thefirmware version of the AP).

Client Service Type Information Element

The client can convey its requested service type via a Service Typeinformation element in a probe request. The access point can convey itssupported service type via a Service Type information element in a proberesponse or beacon. It is worthwhile to note that this can be related tothe Owned/Operated information element. An access point not meeting therequested Service Type from a client may choose not to respond to theprobe request.

An example syntax can be Service Type=UMA (GSM), CDMA, SIP, etc.

Furthermore, if the service type matches in a probe response or beacon,the client can include the service type in the association request (orreassociation request). In this instance, the access point can interpreta successful association as a request to setup a type of service. Asexamples, a UMA phone can need IPSec passthrough, while a SIP phone canneed port forwarding, while either case can need a WLAN to WAN QoSmapping.

Mobile Device Type Information Element

The client can convey its requested device type via a Mobile Device Typeinformation element in a probe request. The access point can convey it'ssupported device types via a Mobile Device Type information element in aprobe response or beacon. It is worthwhile to note that this can berelated to the Client Service information element. An access point notsupporting the indicated Device Type from a client may choose not torespond to the probe request.

An example syntax can be Device Type=Phone, PDA, media adapter, etc.

Furthermore, if the Mobile Device type matches in a probe response orbeacon, the client can include the Mobile Device type in the associationrequest (or reassociation request). In this instance, the access pointcan interpret a successful association as a request to setup a type ofservice. Again, as examples, a UMA phone can need IPSec passthrough,while a SIP phone can need port forwarding, while either case can need aWLAN to WAN QoS mapping. An audio/video device may need different setup.

Mobile Device Manufacturer Information Element

The client device can convey the manufacturer of the client via thisinformation element. Certain services, features, or other items may onlybe available to clients made by certain manufacturers and the accesspoint can make a better decision with this information. Clients withknown issues or incompatibilities can also be avoided.

An example syntax can be cmanufacturer=Linksys (or other descriptor ofthe manufacturer of the client device).

Mobile Device Model Information Element

The client device can convey the model of the device via thisinformation element. Certain services, features, or other items may onlybe available on certain models of clients and the access point can makea better decision with this information. Clients with known issues orincompatibilities can also be avoided.

An example syntax can be cmodel=WIP200 (or other text descriptor of themodel of the client).

Mobile Device Firmware Version Information Element

The client device can convey the firmware version of the device via thisinformation element. Certain services, features, or other items may onlybe available on certain firmware versions of clients and the accesspoint can make a better decision with this information. Clients withknown issues or incompatibilities can also be avoided and the accesspoint or SP can initiate a firmware version. This is especially true ifthe manufacturer, model and firmware version are known, as discussedabove.

An example syntax can be cfirmware=1.2 (or other descriptor of thefirmware version of the client).

Although the present invention is discussed as being used in an 802.11environment, those skilled in the art will appreciate that one or moreaspects of the present invention are suitable for use in other wirelessenvironments. Thus, discussion herein regarding 802.11 is by way ofexample only, and not by way of limitation.

Although the information regarding setup features and services isdiscussed herein as being communicated as part of a probe request, proberesponse, or beacon, those skilled in the art will appreciate that suchinformation may be communicated as part of various other informationunits. For example, the information may be communicated as part ofassociation requests, re-association requests, or any other desireinformation units. Thus, the discussion of the communication of suchinformation via probes requests, probe responses, or beacons is by wayof example only, and not by way of limitation.

Further, the information communicated according to the present inventionneed not be limited to information regarding desired setup featuresand/or desired services. Rather, the information may comprise anyinformation regarding the wireless client, the access point, and/or thenetwork that facilitates enhanced operation of any of these devices,particularly when such information is communicated prior to associationof the wireless client to the network. According to one aspect of thepresent invention, such information is used to select or help select theaccess point (and thus the network) to which the wireless deviceassociates. In this manner, the connection between the wireless clientand the access point can be enhanced. Further, enhanced services can beprovided by the network to the wireless client, on a per client basis.

Thus, one or more aspects of the present invention allow the wirelessclient to learn more detailed information about the access point or thewireless network. For example, the wireless client can learn informationregarding setup features of the access point and/or services offered bythe network. Such information can allow the wireless device tointelligently select the best access point for intended use and may alsoallow the access point to optimize each connection on a per clientbasis, thus providing enhanced service to the wireless client. Thisprocedure mitigates the need to change access point after the wirelessclient has associated to the network due to the unavailability ofdesired setup features and/or services.

According to one or more aspects of the present invention, the accesspoint and/or network can learn more about the wireless client, so as tohelp determine if connection of the wireless client to the access pointis desirable. This procedure also mitigates the need to change accesspoint after the wireless client has associated to the network due to theunavailability of desired setup features and/or services.

Because the information is communicated prior to association, the needto associate to learn the desired information and then possiblyde-associate and subsequently associate elsewhere is desirablymitigated. Further, by configuring the access point to only respond toprobe requests if the access point or the network can provide at leastsome (or alternatively all) of the desired setup features and/orservices, then the wireless client does not have to parse proberesponses from access points for which associated is not desirable.Thus, according to one or more aspects of the present invention, theefficiency, effectiveness, and utility of wireless communications areenhanced.
